Interpretive Signs Designed To Trigger Naturalist Intelligence At Two American Zoos, Martha Bryant
Interpretive Signs Designed To Trigger Naturalist Intelligence At Two American Zoos, Martha Bryant
Graduate Student Dissertations, Theses, Capstones, and Portfolios
An investigation of interpretive graphics was conducted in 2005 at two mid-sized AZA-accredited zoos, Lowry Park Zoo, Tampa, Florida and Knoxville Zoo, Knoxville, Tennessee. The Lowry Park Zoo study investigated signs at a red-tailed hawk and sandhill crane exhibit. Combination signs and wordless signs were more effective helping visitors see animals, increasing holding time, and number of engagements than treatments of no signs, or signs with words only. A second study, at Knoxde Zoo, tested combination and wordless signs in a children's zoo, investigating 31 signs at a 3.5-acre exhibit. Comparisons of visitors seeing the animals/using interactive exhibit elements, holding …
The Defensin Gene In Dermacentor Variabilis And Ixodes Scapularis, Katherine Corbett Seguin
The Defensin Gene In Dermacentor Variabilis And Ixodes Scapularis, Katherine Corbett Seguin
Biological Sciences Theses & Dissertations
In response to microbial challenge, invertebrates rely on their innate immune response to recognize and destroy harmful pathogens. One of the primary proteins produced by the response and that has been observed in many invertebrates, including insects, mussels, and ticks, is defensin. These proteins are responsible for forming pores in the membranes of invading microbes thereby destroying them. This study examined the gene coding region for defensin in two important tick disease vectors, Dermacentor variabilis and Ixodes scapularis. PCR amplification of the genes from tick chromosomal DNA resulted in the amplification of a 225 base pair amplicon. Sequencing of …

Endocrine Disruption In Atlantic Salmon (Salmo Salar) Exposed To Pesticides, Benjamin W. Spaulding
Endocrine Disruption In Atlantic Salmon (Salmo Salar) Exposed To Pesticides, Benjamin W. Spaulding
Electronic Theses and Dissertations
Since the early 19801s, the numbers of adult Atlantic salmon (Salmo salar) returning to Maine's rivers have been in a general decline. In addition, estimates of parr, freshwater smolt and emigrating smolt populations indicate low overwinter survival rates. Overall, these low numbers, along with several other factors, resulted in the Atlantic salmon in eight rivers in Maine being classified as a distinct population segment under the Endangered Species Act. Because many of the listed rivers are found near lowbush blueberry barrens, I investigated the endocrine disrupting potential and effects of selected blueberry pesticides on Atlantic salmon. An E-SCREEN assay was …
A Study Of The Effects Of Probait On Chuditch, Dasyurus Geoffroii, Within The Julimar Conservation Park With Notes On The General Ecology, Melissa York
Theses : Honours
Broad scale fox baiting programs have been underway in Western Australia since 1996 when the Western Shield fauna recovery program commenced with the aim of recovering many fauna species that are under threat of extinction. Until recently, effective fox control for fauna recovery has been achieved with dried meat baits impregnated with the poison 1080. The Department of Conservation and Land Management (CALM) has developed more readily available and cost effective sausage meat baits, termed Probait. As bait acceptability trials in the laboratory indicated a potential risk from Pro bait ingestion by chuditch (Dasyurus geoffroii), assessment of the likely risk …

Nursery Delineation, Movement Patterns, And Migration Of The Sandbar Shark, Carcharhinus Plumbeus, In The Eastern Shore Of Virginia Coastal Bays And Lagoons, Christina L. Conrath
Dissertations, Theses, and Masters Projects
The identification and delineation of nursery areas and areas of aggregation of north Atlantic sharks has been identified as an important information need for future management efforts. The objectives of this project were to use a fishery-independent method to study the overwintering area of juvenile sandbar sharks, to spatially delineate the Eastern Shore nursery area, and to examine movement patterns and space use within this nursery area. Data from 21 satellite transmitters attached to large juvenile sandbar sharks revealed that these sharks primarily occurred off the outer banks of North Carolina, at deeper depths and colder water temperatures during the …
